INKENG MECHANSM.

Application filed .Tune 4, 1921. Serial No. 474,912.

T0 all whom t may concern:

Be it known that I, CLAUDE L. Pos'r, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements inlnking Mechanisms, of ywhich the following is a description.

My invention relates to inking mechanisms, and more particularly-to an inking roll having an ink-receiving reservoir therein which may be conveniently filled, and being provided with means whereby the ink in said reservoir may be fed to the inking surface of the inking roll intermittently.

Another object of my invention is to provide means for reciprocating the inking roll while it is being rotated so that the ink is more evenly distributed on the cooperati g inkingrolls or distributing rolls over their entire surfaces. y

v"Another object of my invention is to provide a device of the character described which may be easily assembled or disassembled for inspection or the like, and which is extremely simple, durable, compact, ein cient Vand satisfactory for use wherever found applicable.

Many other objects and advantagesof the construction hereink shown `and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention-consists in the novel construction, arrangement and combination of parts herein shown and' described, and more particularly pointedv out in the claims.

Fig. 10y is a sectional view taken substantially on line 10 1O of Fig. 8; and

Fig. 11 is a fragmentary plan view of the inking roll shown iny Fig.

Referring to the drawings, wherein 1 have illustrated thepreferred embodiment of my invention, 1 indicates the side frames of a printing mechanism of any suitable or desired construction, said frame having upwardly extending pairs of arms 2 2 at its opposite sides, and there being a slot 3 between each of said pair of arms. Rolls 4., 5, 6, and 7 are suitably held in place or car# ried by said frame, the rolls 4 and 5 being adjustably journaled therein in journal boxes 8, as shown in Figs. 1` and 2. The rolls 4 and 5 are suitably geared together or driven by any suitable means, not shown.

The shaft 9 of the roll yG-is annularly slotted at 10 so as to receive the yoked end 1.1 11 of reciprocating arm 12, said arm being pivoted at its end 13 andadapted to be oscillated on said pivot throughsuitable gearing. The gearing for oscillating the arm 12 comprises a worm gear 14 at the end of arm 17 secured to the frame in any suitable` manner. A `pin 18 projects from the face of the gear wheel 16, and is adapted to slide in a longitudinal'fslot 19 provided in the arm 12, said pin 18 being eccentric to the pivotal axis of the gear wheel 16.y '1t is obvious that as the shaft 15 rotates, the worm 14 will rotate the gear wheel 16 and the eccentrically mounted pin 18 will slide in the slot 19 to oscillate the arm 12 on the pivot 12, this movement being transmitted to reciprocate the roll. 6. i

The inking roll 7 is in frictional contact with thefroll'G, as shown in Figs. 1 and 2, the shaft 20' supporting said roll at its ends. A, bearing sleeve 21- surrounds theshaft 20,

.said bearing sleeve being cut away or recessed between its ends.y as at 22, on opposite sides so as to nonrotatably tit between the kopposed the sleeve andl adjustably secured thereto by f a set screw ,24, or any other suitable 0r equivalent means for the purposeq the collar 23 being recessed on opposite sides, as at 25, and providing Shoulders 26 overlying the opposite sides of the trame arms 2, thus prerenting relative lateral movement therebetweenfbut permitting the sleeve, with its attached collar, to be slid into place down- Wardly between the spaced arms 2, as shown in Fig. l. The collar 23 is of a lesser length than the length between the shoulders or ends of the recesses 22 so that the sleeve may be adjusted relative thereto. i

The inking roll 7 has an inl; well or inkrecehfing chamber 27 therein, said chamber being `formed b v slotting the roll longitudinal ly thereof. said slot opening on the periphery of the roll. Viithin the 'chamber 27 is revolubly mounted a roller 28, supported by a shaft 29 at'its ends, the periphery of the roller being` substantially flush with the peripheral surface of the roll 7, as shown in Fig. 9. At one end of the shaft 29 is mounted a gear or ratchet wheel 30, said gear being adapted to be intermittently engaged by a preferably resilient or yieldable tooth member ll'carried by the sleeve 2l. As the roll 7is in frictional contact With thev roll 6, it is driven and reciprocated thereby. and the teeth of the gear 30 which is eccentric-ally mounted relative to the rotational axis of the roll 7 Will be intermittently yengaged by the laterally offset or projecting' tooth end S2 of theresilient member 3l, las 'shown'in Figs-2 and't.' whereupon the roller 28 'will be. "partially rotated relative to` the'rotation of the'roll 7 so as to carry the'ink `to the periphery of the roll 7 Where it may be distributed to the roll 6 and to the type roll, as desired. 4

The ink reservoir may be closed by. any suitable means, and removably held in place, In the embodiment shown, the cover 33, hav` ing downturned or laterally offset ends 34, is pivotally mounted on the rollf7 `by screws through said ends, or any other equivalent means for the purpose, said cover being arcuate or curved in cross section to conform to the peripheralsurface of the roll 7 and overlying` one edge of the slotted chamber 27.' Thel 'screws nfi'ay,y be tightened to hold the cover firmly' in place.` or any other suit able or preferred latching means. such' as aspringprssed detent, maybe used.'

' l'Whenever it is desired to fill the chamber or to open it for inspection, or for any other desired purpose, the cover is drawn back, as shown by the dotted lines in Fig. 9, Whereupon easy access is had to the chamber 27 and to the parts therein.

Having'thus described my invention., it is obviousf'that various immaterial modiica tionsmay be made in the same Without departing from the spirit vof my invention; hence I do not Wish to be understood as liniiting" myselfto the exact form, arrangement,
